Bean spider mite commonly refers to Tetranychus ludeni, a species in the spider mite family (Tetranychidae) that is a pest on beans and other crops.
Primary host: Beans (Phaseolus vulgaris)
Also affects cotton, eggplant, tomato, cucumber, and other vegetables and ornamentals.
Small mite, generally red to brown in color.
Builds fine webs on the underside of leaves.
Similar in appearance to Tetranychus urticae (two-spotted spider mite) but distinguishable under a microscope.
Causes chlorotic spots or stippling on leaves from sap feeding.
Severe infestations can lead to bronzing, leaf curling, defoliation, and reduced yields.
Webbing can cover entire leaves and plant parts.
Biological control: Predatory mites like Phytoseiulus persimilis and Neoseiulus californicus are effective.
Cultural practices: Remove infested plant debris, avoid excessive nitrogen.
Chemical control: Miticides may be used, but rotation is essential to avoid resistance.
